Dockerfiles

This page describes how to create a custom Docker image for Saturn based on Alpine Linux or Debian.

The Saturn Docker image doesn't contain additional packages to keep the size of the image small.

Alpine Linux

FROM codeberg.org/saturn-sync/saturn:v0.32.1 AS saturn

FROM alpine:3.22
ENV SATURN_DATADIR=/var/lib/saturn
RUN apk add --no-cache ca-certificates-bundle git && \
    rm -rf /var/cache/apk/* && \
    addgroup -g 1001 -S saturn && \
    adduser -h $SATURN_DATADIR -u 1001 -G saturn -S saturn
COPY --from=saturn /saturn /bin/saturn
WORKDIR $SATURN_DATADIR
USER saturn
CMD ["/bin/saturn"]

Debian

FROM codeberg.org/saturn-sync/saturn:v0.32.1 AS saturn

FROM debian:trixie
ENV SATURN_DATADIR=/var/lib/saturn
RUN groupadd --system --gid 1001 saturn && \
    useradd --system --gid saturn --home $SATURN_DATADIR --comment "saturn user" --shell /bin/false --uid 1001 saturn && \
    apt-get update && \
    apt-get install --no-install-recommends -y git ca-certificates && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists/*
COPY --from=saturn /saturn /bin/saturn
USER saturn
WORKDIR $SATURN_DATADIR
CMD ["/bin/saturn"]
